Using it now would incur converting the three x86_def_t vendor words
into a string for object_property_set_str(), then back to three words
in the "vendor" setter.
The built-in CPU definitions use numeric preprocessor defines to
initialize the three words in a charset-safe way, so do not change the
fields to char[12] just to use the setter.

If a guest sets very short timeouts, and asks for a timer to be reloaded on
timeout, QEMU can go to 100%CPU utilisation and become unresponsive,
as it is spending all its time generating timeout interrupts.  On real
hardware this doesn't matter, as the interrupts are just coalesced,
and the effect is to have the interrupt asserted all the time.

This patch is a band-aid, that prevents timeouts less than 10
microseconds from being set.  10 microseconds is a limit that was
determined empirically on a variety of machines as the shortest that
allowed QEMU to pick up a control-a c sequence to get at the monitor.

Now only the qemu_*dir variables will become #defines. The other
directory names aren't used by the C code.

That means the following #defines won't be available in C code anymore:

 - CONFIG_QEMU_BINDIR
 - CONFIG_QEMU_LIBDIR
 - CONFIG_QEMU_INCLUDEDIR
 - CONFIG_QEMU_MANDIR
 - CONFIG_QEMU_SYSCONFDIR
 - CONFIG_QEMU_LIBEXECDIR

The following #defines are going to be kept because they are handled by
the qemu_* block on create_config:

 - CONFIG_QEMU_CONFDIR
 - CONFIG_QEMU_DATADIR
 - CONFIG_QEMU_DOCDIR

This one will be kept because it is set directly by ./configure:

 - CONFIG_QEMU_HELPERDIR

This patch keeps the 'prefix=*' (CONFIG_QEMU_PREFIX) pattern because
other variables may use $prefix on their config-host.mak definitions.
The remaining code will be simplified on a further patch.

$confdir is a confusing name, as it's not clear if it's "the system

$qemu_confdir makes it more clear.
